I'm setting up PX4 on my Crazyflie 2.0. I'm having an issue trying to flash the bootloader using USB. I get the message "dfu-util: No DFU capable USB device available". The cable I am using is a Micro USB -> USB and then I'm using a USB -> USB-C for my Mac.

When I execute the command "dfu-util -l --list", no devices are found.

Can anyone confirm whether this issue is because I am using an adapter rather than a cable straight through?

Are you sure your cable is working for data? (for example usb cables shipped with USB batteries usually do not have the data lines cabled...).

For reference, I tried on our dev mac and without battery, I press the button, connect the USB cable and release the button when the LED blinks fast, I get the bootloader to appear in the system report:
